Speciscation of Letters Patent.

TaaZZ whom if may concern Be it known that I, ROBERT Horn-JONES, asubject of the King of England, and residing at North Tonawanda, in theoountyoi" Niagara and State of New York, have 1nvented new and usefulImprovements in Tuning Devices for Reed-Organ Pipes, of which thefollowing is a specification.

This invention relates to the devices employed for" tuning the tonguesof organ pipes. The device now generally used for this purpose consistsof a sti-called tuning wire passing through the block which carries theeschalot and having its lower portion doubled upon itself to 'forni anarm or linger which bears against the tace of the tongue and is raisedor lowered for tuning the tongue by adjusting the tuning wire in theblock. This wire extends some distance below the block, givinv itconsiderable elasticity, and owing to the trictional resistance betweenits linger and the tongue, the bodyportion of the wire below the blockis sprung or deflected away from the esclialot more or less whenadjusted upwardly and toward the eschalot when adjusted downwardly, inadjusting the wire, vthis deiiecti-on continues until the resultingtension overcomes the frictional resistance of the linger when the lowerportion of the wire recoils and causes' the free end of the nager tojump along the tace of the tongue to a greater or less ein tent. Insteadof promptly and positively following the vertical adjustments ot thetuning wire, the nger is thus shifted to an excessive and uncertainextent, rendering it exceedingly difficult to tune the tongue accuratelyand requiring repeated tapping or adjustment of the wire for thispurpose. But the most serious objection to said tuning def vice is thatthe inger does not reliably re main in adjusted position and often.shifts out of place, because the body of the tuning wire is usuallyunder greater or less tension after effecting the adjustment.

It is the object of my invention to oven come these objections by simpleand inerpensive means.

In the accompanyin drawings: Figure l is a vertical section o? an organpipe provided with niyimproved tuning device. Fig. 2 is a perspectiveview of the tuning device and associated parts.

Similar' letters of reference indicate bor responding parts in bothfigures.

A indicates the body of the organ pipe; B

the eschalot; l; the tongue; C the block in which the eschalotis securedby any suitable means, and D the boot in the. upper end of which theblock is inserted.

E indicates the body or shank of the verticallyadjustable tuning wirehaving the customary arm or finger El terminating in a transverse bar f;which bears against the face of the tongue. The tuning Wire is providedat its upper end with the usual lip or lateral bend el adapted to betapped by a suitable tool for adjusting the Wire, and its body-.portionpasses through a longitudinal opening of the block C. In order toprevent the above-described lateral` detiection of the portion of thetiming wire below the block, l provide therefor a rigid guide bracket orsupport which, while allowing the wire to be freely adjusted up and downin the block, eifectually holdsits lower portion against springing, thuscompelling the linger El to partake promptly and positively in slightand nice adjustments of the tuning wire and permitting ready andaccurate tuning of the tongue, and also reliably retaining it inadjusted position.

'In the preferred construction shown in the drawings, the wireguiding orsupporting device consists of a tube F secured in a longitudinal openingof the block C and extending a suitable distance below the block,preferably nearly to the lower end of the straight portion of the shankE. The portion oic the wire extending below the block is thus guided asrigidly as the portion within the block. As shown, the bore of the tubel" is preferably ot' the proper diameter to snugly fit the tuning iclaim as my invention:

l. A reed organ pipe,comprising a tongue, a tuning wire having a shankand a member arranged at the free end of the shank and bearing againstsaid tongue, and means for holding that portion of the shank adjacent tosaid member against deilection.

2. A reed organ pipe, comprising an eschalet, avblock supporting thesaine, a tongue a tuning-wire having'a linger which bears against thetongue, the body of the tuning` wire being adjustable in said block, anda Patented May 13, 1913.

and extending below the same to :i point opposite the free portion ofthe tongue, and 15 a tuning-Wire having its body portion ndjustablyarranged lin said tube and provided at its lower endI with a fingerbearing against the tongue. Y,

Witness my hand this 2d day of December, 20 1910.
